The JBL L200 was produced in the early to mid 70's, not the 60's, although the studio monitor version was produced earlier. The L-200B (supposidly better) was produced after 1975 I think.
I have a pair of L-166 I modded a bit, this was the "super L-100" and I think is better than the L-100.
Some prefer the Jubal, some the L-150.
I also have a pair of L-200's I restored and replaced internal wiring and jacks. The L-200's are VERY efficient, can get very loud. I bought a vintage Technics 4-band fully parametric eq. specifically to eliminate the peaky presence regions, extend the treble and lower bass.
With high end electronics, these speakers can sort of shine, but in my opinion you must use them close to the back wall, sit very far away, and sit exactly on axis "down the throat" of the high freq. horn. Some prefer the sound without the slatted horn "lens".
